The Special Blue Prize was created as part of the #All4TheGreen Photo4Climate Contest and aimed to select the best photo on the value of water: clean water, dirty water, lack of water, how inadequate access to water and sanitation causes poor health and stunting, how too much or too little water contributes to environmental disasters and human suffering, or how water insecurity can lead to fragility and violence. What is the value of water to you?

Rani, 9, collects rainwater for drinking. Rainwater is the main source of drinking water in the village of Shyamnagar, Satkhira, Bangladesh. Due to sea-level rising resulting from climate change, limited sweet water sources of the coastal area have widely been contaminated with saline water.

Along the beach in Mondouku, Côte d'Ivoire, a group of fishermen have just returned with their catch. Many of them come from neighboring Ghana, and they tell us that they come to the Ivorian part of the coast because there are more fish here. Still, they explain that the fish are smaller in size and number compared to previous years. The beach they are sitting on is lined with small hotels and cabanas destroyed in a storm surges over the past few years. A bit further down the coast, near the Vridi Canal, we speak with Conde Abdoulaye, who runs the lobster restaurant that his father ran before him. Even at low tide, the water laps against the steps of the restaurant and a retaining wall which he has rebuilt numerous times. He says he knows it is inevitable that at some point the sea will swallow his restaurant, and he will have to leave. He blames the canal for most of the beach erosion, but also acknowledges that changing weather patterns and increasing storms have contributed to the damage.

Togolese families often place talismans, thought to contain magical or spiritual properties, outside their homes facing the Atlantic Ocean in hopes of protecting their dwellings from encroaching tides.

Unfortunately, dozens of villages have been devoured since the mid-1990s, leaving behind shells of houses, livelihoods and memories in the wake of a coast receding as much as 5-10 meters per year. When expatriates return to Togo’s coast to visit their childhood homes, they are astonished to see that communities have literally washed out to sea.

A boat trip from Port Elizabeth to Kingstown, in the Caribbean country of Saint Vincent and the Grenadines, is a one-hour trip that locals take several times a day. It was during one of these journeys that the boat of Kamara Jerome, a young Vincentian fisherman, ran out of gas six miles from Bequia City in what is termed locally as the "Bequia Channel." While waiting for help with strong wind gusts and the sun on his head, the idea of developing a boat that would run with wind and solar energy was born. Soon after, the idea became a prototype; a boat using green technology was on the water making 20-year-old Jerome a winner of international innovation competitions and a role model to other Caribbean youth.

In Mexico, young engineer Daniel Gomez runs a multimillion bio-diesel company originally conceived as a research project for his high school chemistry class. Gomez and his partners - Guillermo Colunga, Antonio Lopez, and Mauricio Pareja - founded SOLBEN (Solutions in bio-energy in Spanish) in their early twenties.

Although Daniel and Kamara have different educational backgrounds, they do share one important skill, the ability to identify a problem, develop an innovative solution, and take it to the market. In other words, being an entrepreneur, an alternative to be economically active, that seems to work and not only for a few.

The King Baudouin Foundation has just announced that it is accepting nominations for its 2014-2015 African Development Prize. The Prize awards innovative initiatives that help local communities take development into their own hands and that improve quality of life. The Prize is worth 150.000 Euros and is awarded every other year. Previous winners include women's rights advocate Bogaletch Gebre of Ethiopia and Dr.

Dear Africa Can readers, we’ve heard from many of you since our former Africa Chief Economist Shanta Devarajan left the region for a new Bank position that you want Africa Can to continue highlighting the economic challenges and amazing successes that face the continent. We agree.

Today, we are re-launching Africa Can as a forum for discussing ideas about economic policy reform in Africa as a useful, if not essential, tool in the quest to end poverty in the region.

You’ll continue to hear from many of the same bloggers who you’ve followed over the past five years, and you’ll hear from many new voices – economists working in African countries and abroad engaging in the evidence-based debate that will help shape reform. On occasion, you’ll hear from me, the new Deputy Chief Economist for the World Bank in Africa.

We invite you to continue to share your ideas and challenge ours in pursuit of development that really works to improve the lives of all people throughout Africa.

Here is my first post. I look forward to your comments.

In 1990, poverty incidence (with respect to a poverty line of $1.25) was almost exactly the same in sub-Saharan Africa and in East Asia: about 57%. Twenty years on, East Asia has shed 44 percentage points (to 13%) whereas Africa has only lost 8 points (to 49%). And this is not only about China: poverty has also fallen much faster in South Asia than in Africa.

These differences in performance are partly explained by differences in growth rates during the 1990s, when emerging Asia was already on the move, and Africa was still in the doldrums. But even in the 2000s, when Africa’s GDP growth picked up to 4.6% or thereabouts, and a number of countries in the region were amongst the fastest-growing nations in the world, still poverty fell more slowly in Africa than in other regions. Why is that?
